Fulltext Indexing on MyISAM, single column vs multiple column indexing

旧巷老猫 提交于 2019-12-02 12:04:05

For MyISAM:

FULLTEXT (`column_a`, `column_c`, `column_x`)

For InnoDB:

FULLTEXT (`column_a`, `column_c`, `column_x`),
FULLTEXT (`column_a`),
FULLTEXT (`column_c`),
FULLTEXT (`column_x`)

If you have version 5.6 or later, you should convert to InnoDB.
